An influence of the elemental composition of the amorphous alloy, the shape of its final product, as well as the preparation conditions (cooling rate) according standard technology, on the strength characteristics of tape and bulk samples of alloys made from the same feedstock is investigated. A lower cooling rate in the process of obtaining bulk alloys (10$^3$ K/s) increases structuring of bulk samples, in comparison with tape samples (10$^6$ K/s), and causes higher divergence of surface elemental composition from the original feedstock. Microhardness of the bulk samples is higher than one of tape alloys.

Key words: tape and bulk amorphous alloys, mechanical properties of alloys.
